Abstract
L'invention concerne un procédé d'étalonnage par spectroscopie par claquage induit par laser (LIBS) ou de dosage LIBS qui comporte la fourniture d'une pluralité d'échantillons de référence, ayant chacun une concentration connue respective d'un analyte, le dosage de chaque échantillon de référence pour obtenir un spectre LIBS respectif, et pour chaque spectre LIBS de référence, la mesure d'une intensité d'au moins une ligne d'analyte spectrale qui varie avec la concentration de l'analyte, et la mesure d'une amplitude crête d'au moins une ligne de saturation d'un élément de référence. Le rapport et les concentrations connues définissent une courbe d'étalonnage pour l'analyte.
